Someone who pisses nature. A nature boy can often be found riding his bike to wildlife ecology classes on any nature loving campus such as University of Maine or Unity College. This breed of boy lives in flannel and smokes enough pot to make a columbian drug lord proud and due to excessive time spent hiking through the woods these boys have hot bodies. If you fit the above criteria and have dreadlocks you are the king of the nature boys.
